Superior Corrosion Resistance Enamel Bolted Steel Tank for Sewage water storage
description
The enamel bolted steel tank is a kind of bolted storage tank made from two materials: glass and steel. High-strength TRS (titanium-rich steel) plates and enamels are perfectly fused at high temperatures to form a highly inert inorganic glaze layer. This coating system has excellent anti-corrosion properties and is the best choice for sewage water storage.
Material Characteristics of Enamel Steel Tanks
-Low Carbon, High Strength, High Titanium.
The steel substrate employed in the construction of glass-fused-to-steel tanks is a special high strength enamelled steel with a unique design and superior properties. Its mechanical properties, including yield strength, tensile strength, and elongation, far exceed those of conventional steel sheets.

Uses of Enamel Bolted Steel Tanks
Enamel bolted steel tanks are an ideal match for corrosive wastewater applications ranging from municipal sewage and industrial effluents to livestock wastewater and landfill leachate.
Enamel bolted tanks deliver outstanding performance for sewage & wastewater storage with these core merits:
1.Molecular fused double-sided enamel coating provides superior anti-corrosion capacity, wide pH resistance (1–14), anti-abrasion against silt and H₂S corrosion, service life over 30 years without recoating.
2.Smooth inert glass surface minimizes sludge adhesion and biofilm growth, lowering cleaning & maintenance downtime.
3.Modular bolted assembly enables fast on-site installation regardless of weather, easy volume expansion, disassembly & relocation.
4.Reliable rubber sealing prevents wastewater leakage and odor emission, compatible with membrane roof for closed sewage storage.
5.Lower overall lifecycle cost vs welded steel or concrete tanks for municipal & industrial wastewater treatment projects.
